Buena por esa "nmap" excelente herramienta para ver los puertos, resulta que mande un comando para ver si los puertos estaban abiertos y este fue el resultado:

Código:
nmap -v -A MI_IP_FIJA

Interesting ports on Static-IP-crMI_IP_FIJA.cable.net.co (MI_IP_FIJA):

No exact OS matches for host (If you know what OS is running on it, see http://nmap.org/submit/ ).
TCP/IP fingerprint:
OS:SCAN(V=5.00%D=5/28%OT=21%CT=1%CU=32456%PV=N%DS=0%G=Y%TM=4DE12178%P=i686-
OS:pc-linux-gnu

Uptime guess: 0.002 days (since Sat May 28 11:20:55 2011)
Network Distance: 0 hops
TCP Sequence Prediction: Difficulty=205 (Good luck!)
IP ID Sequence Generation: All zeros
Service Info: OS: Unix

OS and Service detection performed. Please report any incorrect results at http://nmap.org/submit/ .
Nmap done: 1 IP address (1 host up) scanned in 23.86 seconds

No muestro mi (MI_IP_FIJA) ya que este es un servidor de pruebas y no me gustaría una denegación hasta poder configurar iptables.

Por lo que veo creo que es el puerto, que no esta abierto:

Código:
Discovered open port 111/tcp on MI_IP_FIJA
Discovered open port 80/tcp on MI_IP_FIJA
Discovered open port 21/tcp on MI_IP_FIJA
Discovered open port 631/tcp on MI_IP_FIJA
Discovered open port 8010/tcp on MI_IP_FIJA
Habría algún problema si lo hago en uno de estos puertos abiertos excepto el puerto 80, como el puerto 21?

Nota de instalación de nmap en Debian Squeeze:
Código:
# aptitude install nmap
Gracias por la info y la herramienta.
